Do you and should you trust empirical formulae?

Mode = 3 (median) - 2 (mean)The above is an empirical formula of calculating the statistical mode of a data.

I have a few questions:1. What are 'empirical' formulae?2. Is the mentioned formula for mode proved? If not, then how did we come around it?3. 'Mode is that outcome with the maximum frequency' This means that the Mode of the data is definately a member of the set of data. However, if we calculate mode according to the formula, it might not always be one of the members of the data. Any explanation for this?
